The _ is a metric unit of volume
Liter
For ease of understanding, scientists report measurements using the __ system
SI Unit
Whether applications of science to everyday life are considered good, bad, right, or wrong comes under the category of _
ethics
A brain scan is an example of __
technology
The theme that reflects the idea that there has been a gradual change in the characteristics of species over time is __
evolution
Living things adjust to a stimulus by a reaction called a
response
Living things change during lives through
growth and development
All living things __ to make more living things
reproduce
The study of standards for what is right and what is wrong is called
ethics
The information gathered from experiments is called
the data
A scientific explanation of known facts arrived at through repeated testing over time is a
theory
To use data to support a particular point of view
This is NOT a goal of science
Information gathered from observing a plant that grows 3 cm over a two-week period results in
data
using a feeling about what should occur
This is NOT a way scientists generate hypotheses
Scientific hypotheses must be proposed in a way that
enables them to be tested
The ability to reproduce results is an important port of any
experiment
The work of scientists begins with
careful observations
A controlled experiment allows the scientist to isolate and test
a single variable
Scientists publish the details of important experiments so that
their work can be repeated, their experimental procedures can be reviewed, and so that others can try to reproduce the results
The process by which organisms keep their internal conditions fairly constant is called
homeostasis
In the metric system, the basic unit of length is the
centimeter
the gradual change in the characteristics of a species over time
evolution
the living and nonliving factors in an organism's surroundings
environment
Any structure, behavior, or internal process that enables an organism to better survive in an environment
adaptation
An organism's tendency to maintain a stable internal environment
homeostasis
the series of changes that an organism undergoes during its lifetime
development
the process whereby an organism produces more of its own kind
reproduction
its flow through ecosystems determines how organisms interact and powers all life processes
energy
a variety of structural and behavioral adaptations help organisms relate their internal environment
homeostasis
organisms depend on internal and external systems that interact in complex ways to help them perform their life functions
systems and interactions
Over time, gradual changes in structures, behaviors, and internal processes of organisms result in diversity of species
evolution
although different organisms interact within ecosystems to form a stable system, all living things share the same characteristics of life
unity within diversity
biology is a continuous search for information about the natural world
nature of science
